Patented Dec. k27', 1932 narran srATEs PATENT oFFflca CHARLES A.MOSGROVE, OF WATERBURY, CONNECTICUT, ASSIGNOR TO'THE AUTOYRE COMPANY,INC., OF OAKVILLE, CONNECTICUT, A CORPORATON F CONNECTICUT SLDE BUCKLEApplicationV filed June 25,

This invention relates to new and useful improvements in slide bucklessuch as are used on the suspender straps of overalls and the like.

' An object of the invention is to pro-vide a buckle which may be easilyand quickly positioned on a strap and secured thereon.

Another object is to provide abuckle which when positioned on a strapwill not slip or l@ casually change its position when the strap pulledVor tensioned.

A further object is to provide an improved buckle formed from a singlepiece of sheet metal.

rllnother object is to provide a buckle adapted to have a strap passthrough it andv includin novel Vmeans to receive and secure an end ofthe strap to the buckle.

Other objects and advantages will become 2O apparent from aconsideration of the following detailed description taken in connectionwith the accompanying drawing wherein the invention is shown. It is tobe understood however, that the invention is not limited the spirit ofthe invention and the scope of' the appended claims to which claimsreference is to be had for a definition of the invention. l

convex in cross section whereby t0 add rigidity to the frame.

Formed with one of the end barsor members, as for example with the endbar 13 is a'v cross member or central bar 15 extending longitudinally ofthe frame of the buckle and in the direction of the end bar 14 of theframe. The cross member 15 is of general U-shape in cross section andincludes a connecting portion 16, side walls or arms 17 and laterallongitudinally extending flanges 18.V The flanges 18 are preferablycontinuations of thev y side or arm portions 17 and located at the freeedges thereof. Prior to the buckle being applied to a strapthe crossmember 15 occupies a posi.

tion relative to the frame 10 substantially as shown in Figs. 4C and 5of the drawing. yHere it will be noted that the cross member inclinesoutwardly away from the frame whereby there is a space 19 between thefree end of the cross member and the adjacent portions of the frame ofthe buckle.

At its free end the cross member 15 car-l y ries a pair of lugs 20,which lugs extend in the directionV of the frame as clearly shown inFig. 5. vExtending inwardly Afrom the end bar 14: of the frame is a lug21. This lug ispreferably formed with the frame as is the cross member15 and during the forma-l tion of the cross member 1t is drawn slightly.

so as to vdispose its free end over the lug 2 1 whereby on the crossmember being pressed in the ldirection ofthe frame its free end will bedisposed vagainst the lug 2 1 so `that the lugs 2O may be wrapped aboutthe lug 2 1 as clearly shown in Fig. 6. l

,The portion 16 of the connecting member 15 has portions lanced andpressed therefrom to provide teeth or clamping members 22 .each

- of the central bar to the frame and then the about the lug 21,

In applying the invention to a strap the Vbuckle is slipped on to astrap from the edge thereof by inserting the edge of the strap into thespace 19 between the frame and the cross member 15 as shown in Fig. 1.rlhe strap may then be drawn into the buckle or the buckle may be drawnacross the strau so as to dispose Vthe edges of the strap beneath thecross memberl 15.

After the edges of the strap are disposed within the frame, and asmatter of fact inwardly of the Vlugs 2O of the crossmember 15, the strapis doubled upon itself to ferm a loop 24rv'hich may support an eye othermeans'for co-operating with a button. The end of the strap is theninserted. beneath the teeth and the entire assembly placed in a. die.VIn the lie the cross member 15 is pressed in the direction of the frameto have its lugs Q0 embrace the edges of the lug 2,1 on theframe and thesaid lugs 2O are wrapped about the lug 21 as shown in Fig. 6. BuringVthis same operation the teeth 22am forced in the direction of the crossmember wherebyto clamp the material of the strap against the crossmember. Gr if preferred, after the strap is inserted under the centralbar 15, or that is between it and the frame the free end of this bar maybe pressed down into the frame and secured by folding the lugs 2O aroundthe opposite edges of lug :21 as shown in Fig. 6. This securely fastensthe free end end of the. strap may be-clamped under members 22 by aseparate operation. A

Attention is directed to the fact that the improved buckle may be easilyand quickly applied to a strap and in connection with Fig.

' 3 it will be noted that the cross member 15 is so constructed that`the longitudinally extending ilanges 18 occupy a position somewhat tothe 'rear of the frame when the cross member is secured by having itslugs 2O bent A Therefore, there is considerable of an off-set in thestrap 23 and the strap will not slip through the'bluckle on the strapbeing pulled. To adjust the buckle on the strap it is first necessarytov draw thel strap through one side of the buckleY or beneath one ofthe side bars of the buckle andV to then take up the slack by drawingthe slack through the other side of the buckle.

There is no casual or accidental slipping of the buckle.

insane Figs. 7 and 8 show a slight modification of the buckle of theinvention and in this form of the invention teeth 25 are pressed fromthe connecting portion 16 of the cross member 15. However, a certainamount of material is removed as at 27'about the teeth and when thestrap 23 is positioned beneath the teeth the teeth are pressed back intothe plane of the portion 16 of a connecting member as clearly shown inFig. 8, whereby portiens 2S of a strap 23 are carried downinwardly ofthe outer surface of the connecting member and the end of the strapsecurely attached to the buckle.
